An investigation of the structure of the active mass of the negative plate of lead—acid batteries

摘要: Abstract The formation of the negative plate lead—acid battery has been shown to take place in two stages. During first stage, lead monoxide and basic sulphates are partially reduced react with H 2 SO 4 give PbSO . These processes proceed at a neutral pH. SEM micrographs show that crystals interlinked skeletal primary network form on surface this structure. second is under acidic conditions. Lead precipitated skeleton secondary structure different from skeleton. Upon discharge, current generated mainly expense oxidation crystals. functions types structures have identified. (skeleton) serves as both collector mechanical support obtained during stage. (energetic) participates charge—discharge plate.
